To all'fwho'n it may cof/warn;-

Be it known that I, GEORGE W. BEADLE, a

A' citizen of the UnitedStates, residing at -Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Closures for Vessels; and I do hereby declare the followingto be a full, clear, andexact description of the' invention, such as will enable 'others' skilled Ain the art to which it appertains to make and use the same.

My invention relates tol improved closures for vessels, andit consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide A an improved closure which will 'provide a' protective covering forlthe pouring lip of a vessel andI prevent'the accidental entrance of extraneous matter during removal ofv the closure, and which is adapted to be readily removed and replaced to. permitusuccessive` removalsof portions of the vessels contents.

' part of this application andJ in which correspending reference symbols indicate similar parts in the several views :1

Figure 1 is an elevation, partly in section, illustrating one embodiment of my in- ,ventiong Fig. 2-is a view similar to Fig. 1,

showing the elastic, stretchable, annular,

apron snapped into inverted position for unclamplng. the closure; lFig. 3 is an enlarged detail section of the closure locking 'and clamping means; and, Fig. 4 is an enlargeddetail section, illustrating the manner of removing the closure.

s Reierring to the drawings 1 indicates a cylindrical vessel body of suitable mate' Ifly .having its edge, -or pouring rim, 2

i crimped inwardly to provide an' annular vlocking shoulder 3. A'closurefi of Asuitable ibrous, flexible material, suchjas paper, is shown compris-.-

ing a flexible disk formed with a peripheral fr beads-ofa diameter greater than` theinner .diameter of said annular. shoulder 3, and ,adapted ltobe iexed into'locking positipn- E past said annular shoulder. An integral, *annular apron 6 extends from said bead 5 over tlie'edge of the vessel and depends into A close` engagement with the exterior of said -vessel for lockingly clamping the closurev in position; this provides a very advantageous and eiicient lock for preventing accidental displacement of the closure through yielding of its flexible disk, or, in the case of flexible vessels, through springing of the Walls of the vessel.V y v,

,My improved closure can be advanta-f geously'formed of paper of suitable toughness a'd exibility, whichlisspun intoits,A locked and clamped positionI upon the vessel., whereby the material .is permanently This improvedconstruction of fibrous,

set. iiexible material, provides an elastic, stretchable', annular clamping apron A6 'which isl adaptedfto begreadilyY snapped without dis? ruption' into inverted position for unclamping said closure, as shownin Fig. 2; thereby enabling the closure to@i be readily removed and replaced for permitting successive removals of portions of the vessels contents.

-When theapron 6 has bee thus 'snapped to unclamped position, the closure can be readily removed by pressing saidv apron inwardly to flexthe closure disk for permitting withdrawal of the latter -from its locked position past the locking shoulder 3.

Itfwill be notedthat myimproved closure provides a protective covering for prevent# ing contamination of the pouring lip ofthe vessel, and that theinverted annular apron provides a cup for entrapping any dirt which may A havecollected on the closure. Furtherkthe' stretching of the elastic annu,- lar apron V6 in initially` removing the closure .will 'cause minute surface cracks in said apron,J thereby clearly indicating that the v vessel has been opened. I Y l,

I have illustrated preferred and satisfac- A tory constructions, 'but changes 'could' be made within thefspirit and jscope lofimy ir-A vention.) l p The combination ofv a've'ssel having an vinternal .loclng' shoulder, and.` aj closure provided with a locking member adapted' to engageA said shoulder, and-With an integrah elastic. .stretchable, Aannular apronv adapted to closely t'thejexterior of said vessel for lockngly' clampingsaid closure in` position and to bevreadily snapped into inverted position for unclamping said closure.

2. The 'combination of a cylindrical vessel having an annular shoulder Within its edge, and a closure of fibrousA material provided With a flexible looking disk ofl a diameter greater than the interior diameter of said annulary shoulder, and With an integral,

elastic, stretchable, annular apron adapted to extend over said edge and .depend into en- I gfagement with the exterior of saidve'ssel for lockingly clamping said elosiire in position and to be readily snapped into inverted position above said edge for uncl'amping said closure.

In testimony whereof, I affix my signature, in presence of two Witnesses.
